The GMA2975C is a red and green light source module ideal for both indoor and outdoor displays. It is a singulated dot matrix and cluster module, made up of individual pixel-by-pixel LEDs that are arranged in a "dot matrix" format. These clusters are controlled via a single three-wire serial interface.

The GMA2975C is used for a range of applications, from advertising displays to text, graphics and video displays. Its individual pixels and clusters can be used to create a variety of animation and display effects. The GMA2975C is designed for efficient operation and low power consumption, and its small size makes it ideal for use in tightly space environments.

The GMA2975C is capable of displaying both red and green light source. The module can be configured to be modulated synchronously or asynchronously, with a continuous operating frequency of up to 150KHz. Multiple modules can be connected together in a daisy chain to create larger displays. Additionally, the GMA2975C is capable of displaying a single character or a full image.

The working principle of the GMA2975C is based on the use of constant current LED drivers. These drivers allow for the current to be maintained at a constant level, regardless of changes in temperature or voltage. This ensures that the intensity of the LED clusters remains consistent and uniform. The LED clusters are then turned “on” or “off” using a three-wire serial digital interface.

The digital interface of the GMA2975C is controlled by a single signal source. This signal source can be a PC or any other type of controller. The serial digital interface sends a sequence of 1’s and 0’s to the GMA2975C that tells it how to convert the signal into visible light. The light emitted by the clusters is then put together to create animations or a static image. This allows for a dynamic display, with content that can be changed at any time.

The GMA2975C is a powerful module for creating dynamic, interactive displays. Its user-friendly interface, low power consumption, and small size make it a great choice for both indoor and outdoor applications. Its ability to respond to changes in temperature and voltage also make it an ideal solution for many display needs. Whether used for advertising, graphic displays, animations, or video, the GMA2975C is an effective and efficient way to get the message across.
